The specific embodiment
A kind of diagnostic ultrasound equipment is provided according to an aspect of the present invention, it is characterized in that, comprising: ultrasound probe; Ultrasonic scanning portion is via inside and the repeated collection echo-signal of ultrasound probe by the detected body of ultrasound wave multiple scanning; Image production part generates the data of a plurality of blood-stream images based on echo-signal; The interpolation handling part, determine that from above-mentioned blood-stream image clutter component is the pixel value of overriding at least one pixel, according to the blood-stream image of the interpolation object that comprises above-mentioned determined pixel roughly the same clap with the heart time corresponding at least 2 other blood-stream images pixel value carry out interpolation.
Clutter noise has the low character of time continuity (time continuity).In other words, clutter noise has momentary (transitory) high character.Clutter noise is change greatly along with the variation of time.On the other hand, the blood flow component has the strong character of time continuity.Present embodiment utilizes the difference of these character to reduce clutter noise effectively.When clapping at each heart, divided by the group mutually a plurality of blood-stream images.A plurality of blood-stream images of same cluster are arranged constantly according to scanning.Clutter noise is spatially in time all by discrete thus.That is, divide and arrangement by this group, the low time continuity of clutter noise is emphasized.The blood-stream image that comprises clutter noise is configured between the blood-stream image that does not comprise clutter noise.Therefore, Filtering Processing can reduce clutter component effectively.
Fig. 1 shows the structure of the diagnostic ultrasound equipment relevant with present embodiment.Diagnostic ultrasound equipment has ultrasound probe 1.Ultrasound probe 1 has: receive from the driving signal of the transtation mission circuit 21 that sends receiving element 2 and produce ultrasound wave and will be transformed to a plurality of piezoelectric vibrators that the one dimension of the signal of telecommunication is arranged from the echo of detected body; The matching layer that is provided with in this piezoelectric vibrator; Prevent from this piezoelectric vibrator back lining materials etc. of propagate ultrasound waves rearward.When from this ultrasound probe 1 after detected body sends ultrasound wave, reflect successively on the discontinuity surface of the acoustic impedance that this transmissions ultrasound wave is organized in vivo, and received by ultrasound probe 1 as echo-signal.The amplitude of this echo-signal depends on the poor of acoustic impedance in the discontinuity surface that has produced reflection.In addition, the echo the when ultrasonic pulse that is sent is reflected on the surface of blood flow that is moving or heart wall etc. depends on the velocity component of the ultrasound wave sending direction of moving body according to Doppler effect, thereby is subjected to frequency shift (FS).
Receiving circuit 22 has: preamplifier; The A/D changer; Receive delay portion; Adder etc.Preamplifier will be amplified by each passage via probe 1 echo-signal that is taken into.Receive delay portion provided the needed time delay of echo-signal decision reception directivity of amplifying, and carries out addition then and handle in adder.By this addition, emphasize reflecting component from the direction corresponding with the reception directivity of echo-signal, form the synthesized beam that ultrasound wave sends reception according to receiving directivity and sending directivity.
By the control of scan control section 3, transtation mission circuit 21 and receiving circuit 22 repeat the ultrasonic scanning of two-dimensional cross-section.During repeating ultrasonic scanning, by operator ultrasound probe 1 is moved on the surface of for example corresponding with the heart of fetus parent at leisure, scan the 3D region of the heart that comprises fetus.This scanning is called 3-D scanning.In addition, in the present embodiment, alternately repeat B mode scanning and color Doppler mode scanning.
B mode treatment circuit 4 obtains echo-signal from receiving circuit 22, and implement logarithm amplification, envelope detection processing etc., reflect the in-built so-called B mode image data (form view data) that show signal intensity with the light and shade of brightness thereby generate with brightness flop.Two dimension (2D) image processing part 11 is luminance picture or coloured image with two-dimentional display object image transformation.
Color Doppler mode treatment circuit 5 carries out frequency resolution according to the echo-signal of being obtained from receiving circuit 22 to velocity information, extraction generates the so-called color flow angiography data (color flow mapping data) (blood-stream image data) that show the spatial distribution of average speed, variation, power etc. with color by blood flow that Doppler effect produced or tissue, contrast agent echo component.
Organism computation of Period circuit 6 periodically carries out the object organ of metamorphosis according to the data fetch of aspect graph picture (B mode image), extract the myocardial contours (cardiac muscle contour) of fetus at this, based on myocardial contours through the time the heart when changing the scanning of differentiating each aspect graph picture phase when clapping.Also can replace organism computation of Period circuit 6, the phase when heart when measuring the scanning of each image by the ecg scanning instrument is clapped.When clapping, the heart differentiated is fed into group of pictures handling part 7 together with the data of corresponding blood-stream image in organism computation of Period circuit 6.
In addition, in Fig. 1, use the B mode image to resolve the organism cycle, but use color doppler image also can resolve the organism cycle.
When a plurality of blood-stream image groups that group of pictures handling part 7 regularly will be generated in color Doppler mode treatment circuit 5 according to scanning turn to and clap with a plurality of hearts corresponding respectively mutually a plurality of groups.Group of pictures handling part 7 is regularly arranged a plurality of blood-stream images that constitute each group according to scanning.The blood-stream image that constitutes same cluster comes from roughly when clapping with one heart mutually collected echo-signal in the scanning of phase.Constitute the blood-stream image of same cluster, the heart is clapped the cycle difference.The so-called heart bat cycle be meant ecg wave form for example from the R ripple to next R ripple during.The so-called heart is meant the position of the heart in the bat cycle mutually when clapping.The typical case is meant that the heart is clapped the cycle equalization is divided into 100, and shows the time phase of the position of the heart in the bat cycle with percentage ratio.
For the relatively main threshold value that is predetermined according to the clutter noise level of parent of pixel value, the pixel (clutter component is overriding pixel (a pixel which clutter elementsoccupy the majority of a pixel value)) of determining to have the pixel value that has surpassed this threshold value connects to the zone of (single lump) (clutter zone candidate) to clutter zone calculating part 9 from each blood-stream image.Clutter zone calculating part 9 as being that the clutter zone candidate that reason needs interpolation to handle compares with the threshold value that is predetermined to have the size that spatially hinders identification blood flow zone, will having the volume of determined clutter zone candidate or area the volume that surpassed this threshold value or the regional candidate of clutter of area and determine to be the clutter zone of interpolation object.
Pixel value in the clutter zone of the interpolation object that blood flow interpolation handling part 8 will be differentiated in the calculating part 9 of clutter zone is replaced into the value that pixel value calculated according to the blood-stream image of same cluster.That is, blood flow interpolation handling part 8 with scanning regularly and the blood-stream image that comprises the interpolation object pixels be the roughly the same heart when clapping mutually and across the blood-stream image that comprises the interpolation object pixels and the heart is clapped the pixel value of the respective pixel of tandem 2 blood-stream images of cycle and come pixel in the clutter zone of interpolation interpolation object.Also can carry out interpolation according to the blood-stream image more than 4 that the heart bat cycle more than 4 that with the heart bat cycle corresponding with the blood-stream image of interpolation object is the vicinity at center is obtained handles.
Three-dimensional (3D) image processing part 10 bases comprise the data by the different a plurality of blood-stream images of the scanning position of the 3-D scanning of the blood-stream image of blood flow interpolation handling part 8 interpolations, generate volume data or arbitrary cross-section image (MPR).
Digital scan converter (DSC) 12 according to monitor 13 corresponding video scanning mode conversions in the form view data that two dimension is generated in (2D) image processing part 11 and the volume data or the cross-section image data that in three-dimensional (3D) image processing part 10, are generated and exported.
Below, the action of present embodiment is described.As shown in Figure 2, in the present embodiment, under the control of scan control section 3, by transtation mission circuit 21 and receiving circuit 22, repeat the ultrasonic scanning of two-dimensional cross-section, meanwhile by operator's mobile probe 1 slowly on the surface of for example corresponding parent with the heart of fetus.This scanning is commonly referred to as 3-D scanning.As 3-D scanning, be not limited to manual type, also can be the electrodynamic type that mechanically shakes the probe of the mechanical type of probe or a plurality of piezoelectric vibrators that use has two-dimensional arrangements and shake scanning plane electrically with a plurality of piezoelectric vibrators that one dimension arranges.
In the present embodiment, alternately repeat B mode scanning and color Doppler mode scanning.Phase when the B mode scanning differentiates that according to the metamorphosis of the heart on its B mode image the heart of fetus is clapped by organism computation of Period circuit 6.Pixel utilization and its corresponding threshold in the myocardial region of fetus are extracted, and its size can come degree of precision ground to differentiate according to the scope of a certain degree relevant with the size that can be envisioned for heart of fetus.Because heartbeat, its form periodically changes certainly.Therefore, phase in the time of can the scanning of each B mode image regularly being defined as the heart and clapping according to metamorphosis.And, owing to alternately repeat B mode scanning and color Doppler mode scanning, thus the periodic heart of the scanning of blood-stream image when clapping with this color Doppler mode scanning before equivalence roughly mutually during the heart bat of B mode scanning of (or afterwards).
When a plurality of blood-stream images of phase are clapped at each heart by group of pictures handling part 7 when having determined that by organism computation of Period circuit 6 heart of fetus is clapped according to scanning regularly and the quilt groupization.That is, as shown in Figure 2, a plurality of blood-stream images are classified into a plurality of blood-stream image groups when clapping according to the heart of the heart of fetus mutually, and regularly arrange according to scanning at each blood-stream image group.
Secondly, by clutter zone calculating part 9, each pixel value (any in speed, variation, the power) of each blood-stream image is compared with the threshold value that is predetermined according to the clutter noise level respectively.The pixel (clutter component is overriding pixel) that will have a pixel value that has surpassed this threshold value connects to one zone and is defined as clutter zone candidate.The clutter zone candidate of determining compares with the threshold value that is predetermined at its volume or area.The clutter zone candidate that will have the volume that surpassed threshold value or an area is differentiated and is the clutter zone of interpolation object.This is that little clutter zone does not hinder the identification in blood flow zone, and on the other hand, the clutter zone candidate with size of a certain degree hinders the identification in blood flow zone.
As shown in Figure 5, by blood flow interpolation handling part 8, the interpolation value that pixel value calculated of the pixel of the same position in the blood-stream image of the front and back that the pixel value of the pixel in the clutter zone of being differentiated is replaced in the arrangement of the group of pictures of the blood-stream image that comprises its interpolation object, adjoin according to the blood-stream image with the interpolation object.That is the pixel value of interpolation subject pixels, be replaced into according to scanning regularly and the blood-stream image of interpolation object be that the roughly the same heart scans regularly the interpolation value that pixel value calculated of the respective pixel in tandem 2 blood-stream images when clapping mutually and across the blood-stream image in the clutter zone that comprises the interpolation object.
Pixel value (the S of the blood-stream image of interpolation object
X, y, z) as the pixel value (S of the pixel of the same position in the blood-stream image of the front and back adjoined
X, y, z-1), (S
X, y, z+1) meansigma methods, pass through S
X, y, z=(S
X, y, z-1+ S
X, y, z+1Calculate)/2.In addition, the meansigma methods of 2 frames before and after this has calculated as typical example, but also can calculate 3 or 4 meansigma methodss that frame is above.
Thus, can eliminate the clutter zone effectively.As shown in Figure 3, generally speaking, the less free seriality of clutter noise, momentary in other words tendency is strong.On the other hand, the strong tendency of the free seriality of blood flow component.As present embodiment, as shown in Figure 4, arrange blood-stream image when clapping mutually according to each heart, thereby spatially or the time go up to disperse to comprise the blood-stream image of clutter noise, the typical case, clutter noise only appears on the frame in each group, is difficult to occur on the frame before and after it.In addition, the blood-stream image of phase calculates interpolation value when clapping with one heart mutually by utilizing, thereby makes interpolation value not become the value that departs from true value more greatly.Therefore, can effectively reduce the clutter noise component, and can carry out interpolation by the high interpolation value of dependability.And then carry out interpolation by the big clutter zone of influence that is confined to hide blood flow, and handle man-hour thereby can reduce interpolation, can use the pixel value that does not have clutter component or clutter component blood flow part seldom in former state ground simultaneously.Fig. 6 is primary blood-stream image, makes among Fig. 7 to be shown in broken lines the clutter zone of being differentiated.Implement the result that interpolation is handled by present embodiment, as shown in Figure 8, the blood flow part of can't see because of clutter (arrow part) is restored as can be known.
Although described certain embodiments, these embodiment only present by way of example, do not attempt to limit the scope of the invention.The method and system of novelty in fact described herein can embody by various other forms.In addition, under the situation that does not break away from spirit of the present invention, can carry out various omissions, replacement and change to the form of method and system described herein.Appended claim and equivalent thereof attempt to cover this form and the modification that will fall in the scope and spirit of the present invention.
